Who Is It For?

B3g-new Genes For Old Flashcards Preview

What is selective breeding?

-select the ones with the best characteristics-breed them with eachother-continue this process over several generations

2

What are the problems with selective breeding?

Reduces gene pool leading to inbreeding-harmful recessive characteristics will accumulate-lack of variation

3

What is genetic engineering?

Transfer of genes from one organism to another so that it produces useful biological products

4

What are the advantages of genetic engineering?

You can produce organisms with new and useful features very quickly

5

What is a disadvantage of genetic engineering?

Inserted genes may have unexpected harmful effects

6

What are some examples of genetic engineering?

1) taking genes that control beta-carotene production and putting it into rice. Humans convert carotene into vitamin A(solving vitamin A deficiency)2) gene for human insulin production is put into bacteria. Bacteria produces insulin then it is extracted3) transferring resistance to disease to useful plants like crops
